The US has about 90 tons of weapons-capable plutonium, while Russia has 128 tons. [1] The US declared 60 tons as excess, while Russia declared 50 tons excess. [1] The two sides agreed that each would eliminate 34 tons. [1] The agreement regulates the conversion of non-essential plutonium into mixed oxide (MOX) fuel used to produce electricity. [2]
As early as 1910 in Russia, independent research was being conducted on radioactive elements by several Russian scientists. [6]: 44 [7]: 24–25 Despite the hardship faced by the Russian academy of sciences during the national revolution in 1917, followed by the violent civil war in 1922, Russian scientists had made remarkable efforts toward the advancement of physics research in the Soviet ...
Zheleznogorsk is also the location for the production of plutonium, electricity and district heat using graphite-moderated water-cooled reactors. The last reactor was shut down permanently in April 2010. [10] It is the location of a military reprocessing facility and for a Russian commercial nuclear-waste storage facility.
To reduce the concentration of Pu-240 in the plutonium produced, weapons program plutonium production reactors (e.g. B Reactor) irradiate the uranium for a far shorter time than is normal for a nuclear power reactor. More precisely, weapons-grade plutonium is obtained from uranium irradiated to a low burnup.
He did not steal a large amount of plutonium, only rags used for wiping surfaces and a small amount of liquid waste. [1] [2] At least two people (besides the criminal) were contaminated by the plutonium. [3] Two flats in Landau in the Rhineland-Palatinate were contaminated, and had to be cleaned at a cost of two million euro. [4]
Watchdogs are raising new concerns about legacy contamination in Los Alamos, the birthplace of the atomic bomb and home to a renewed effort to manufacture key components for nuclear weapons. A ...

It was thought that if a plutonium gun-type bomb could be created, then the uranium gun-type bomb would be very easy to make by comparison. However, it was discovered in April 1944 that reactor -bred plutonium ( Pu-239 ) is contaminated with another isotope of plutonium, Pu-240 , which increases the material's spontaneous neutron-release rate ...
